Understanding the Evolving Nature of Urban Flood Risks in Sub-Saharan Africa: The Case of Kampala City, Uganda

Abstract

The escalation of urban flood occurrences in Sub-Saharan African cities necessitates a nuanced comprehension of evolving flood catalysts beyond the realms of large-scale rapid urbanisation and climate change discourse. Whilst current research and policy discussions primarily focus on these aspects, urban flooding remains a persistent challenge for stakeholders. This chapter addresses this disparity by presenting a precise alternative conceptual lens for understanding changing flood triggers. Through a multimethod approach involving key informant semi-structured interviews and web-based surveys supported by policy review and GIS, the study examines Kampala City as a case study. The findings highlight the intricate interplay of socio-economic, institutional, environmental, and infrastructural factors within diverse socio-spatial contexts and urban dynamics and processes. By emphasising context-specific drivers, the chapter advocates for tailored flood risk policies, urging urban authorities to move beyond ‘onesize-fits-all’ approaches for sustainable flood risk management in African cities.
